Hi Everyone! This sale is for one vintage Mullard GZ34/5AR4 rectifier tube made in Great Britain with gray plates. The tube has its plastic key way missing and the pins are bent some (see photo 3) but tube still plugs into a socket ok and functions. The logo is mostly wore off. The tube was tested on mySencore MU150 Mutual Conductancetube checker and it tested good for emission (emissionis 99%) with no shorts or gas or leakage. I will guarantee the tube to be as I describe it however I cant guarantee the tubes actual performance and life as it can vary depending on application so offer accordingly.Great spare for your hifi or guitar amplifier! Look at the photos and email with your questions. U.S.buyer pays $4.25 first class parcel shipping including tracking.International shipping will befirst class mailand I have a first class calculator listed above. Thanks for looking!
